10 Best Anemometers Reviews & Ratings
When we think of anemometers, we envision a gadget that only scientists and professionals would use, and not something for the common man. However, the reality is that the common man has as much to gain from owning an anemometer as much as the professional as they can help with activities outdoors and on construction sites.

But what is an anemometer? This is a wind speed meter that measures the air velocity, that is the speed of air, and they can be basic cheap handheld units or portable weather stations that calculate more than wind speed. Some fully fledged anemometers can provide hyperlocal weather forecasts to find out if the weather is on your side for your outdoor activities.
Stick around for our buying guide and recommendations, but first, here are fields where an anemometer could be used.
✓ For firefighters – When dealing with wildfires, the wind direction and velocity is a matter of life and death. The reason for this is because wildfire speed and direction changes with a change in wind velocity and direction. Moreover, by getting the temperature and humidity level in the area, they can tell how fast the nearby tinder will catch fire. With this information, they can draft plans to stay safe, and be more effective and extinguish the flames more quickly.
✓ For HVAC specialists – HVAC professionals can measure how fast air from the HVAC is flowing and tell if it is faulty.
✓ Other outdoor activities – Hikers and backpackers will benefit from owning an anemometer as they get instant hyperlocal forecasts that tell them when it is time to seek shelter. Sailors, plane enthusiasts, hunters, sport shooters, etc., will do well with hyperlocal weather information.

There are two types of anemometers, and each has its pros and cons. First, determine your budget and where you plan to use the gadget as these will influence the device that is best for you. First, we have the weather station anemometers. These units are equipped with cups that spin when they catch air and give an accurate reading after multiplying the number of rotations by four. However, they are pricey, and though they can be set up on a console, they are designed to be mounted on a pole.
Other than the weather station devices, there are digital anemometers and differ in price depending on the features. Most digital anemometers are handheld and are lightweight and easily portable for outdoor activities. Moreover, they are easy to read as they are digital units. These appliances use a small fan that rotates when it catches a gust of air.
When investing in an anemometer, you should know how you will use it. If it’s for research purposes, we recommend you purchase in a weather station unit as it is more reliable and accurate.
However, for other activities such as sailing, kite flying, backpacking, etc., we recommend the digital units as they are easy to read, can provide more information, and are portable.
Range and battery power
The range of digital devices vary, and often you have to pay more for longer ranges. However, the range is vital for activities such as sport shooting where you want to measure the velocity at the target. Experts suggest you get a gadget with a range of 5,000 feet as then you don’t have to stand in the gust of wind to get accurate results.
As for power, most anemometers are battery-powered, and you will have to change the battery at least once in the life of the tool. However, look for units that have a power saving mode, and include indicator lights for when the batteries are almost out. S
Though anemometers are designed to measure speed, digital units can do more. However, these additional features will cost you extra. For outdoor enthusiasts, we recommend you pick a device that can measure temperature and wind chill. Firefighters, on the other hand, will appreciate one that can measure temperature and humidity.
Moreover, a unit with properly marked buttons is always valued and more so if there are several functions. Finally, digital units have protective tops to guard the digital display.
How do they work?
Anemometers measure wind speed using the mathematical relationship between the speed and current. These tools function like wind turbines only that their rotor blades rotate at a much faster rate.
The blades rotate a generator which produces an electric current that is now used to calculate the speed.
Can I replace an impeller or a broken sensor?
Well, this depends on the unit. Replacing a broken impeller is much easier on pricey units, and some do allow you to repair a broken sensor. However, the same cannot be said of lower cost units. Often you will have to replace the anemometer due to lack of parts or the manufacturers do not allow repairs.
How accurate is an anemometer?
Again, this depends on the unit you invest in. As a rule, anemometers are accurate between 1% and 5% and the price increases with an increase in accuracy.
We recommend units with a 1% accuracy for professionals and others in high-risk environments where precision could save one from grave injuries, and tools with a 5% accuracy are for amateurs and hobbyists.
How long will the batteries last?
Battery life depends on the usage of the unit. Nevertheless, you can expect it to last about 300 hours of continuous use as has been reported by users and professionals. However, we recommend you get an anemometer with auto power off as it will save your battery.
The areas where an anemometer can come in handy are endless but are mostly used in weather stations to predict weather changes. However, there are fields and activities where having hyperlocal weather data is helpful. Sailors, hikers, backpackers, mountaineers, etc., should have an anemometer as an essential requirement.
Though we cannot help you pick a device, the guide above should make it easier. Finally, if you feel there is something we missed, please let us know in the comments below.
